SPECIFICATION forming part of Letters Patent No. 744,240, dated ovember17, 1903.

Application led December 8,1902. Serial No. 134,432. (No model.)

To all whom, t may concern:

Be it known that we, WILLIAM RossET'rER, of 47 Hancock street, andRICHARD TALBOT, of 3 Hardman street, Blackburn, in the county ofLancaster, England, have invented a eertain new and usefulWeft-Replenishing Loom, of which the following is a specication.

Our invention relates to improvements in automatic shuttling motions oflooms for weaving; and our object is to construct a simple motion whichwill automatically effeet the change of shuttle when required withoutstopping the loom, thereby obviating the necessity for additional brakepower, which is very undesirable and destructive.

In carrying out our invention we employ any suitable mechanism, butpreferably'an improved motion of our own invention, for giving a slowmotion to the loom during the time that the shuttle-changing motion isin action to eject the spent shuttle While the lathe is on the frontcenters and to insert the full shuttle while the lathe is on the backcenters. The loom is then started atV full speed and has approximatelythree-quarters of a revolution of the crank-shaft in which to acquiresuiiicient momentum to insure the shuttle being driven across the shedat the Iirst stroke of the picking-stick after the change.

In lthe accompanying five sheets of drawings, Figure 1 is an endelevation. Fig. 2 is a front elevation; and Fig. 3, a plan view of themain portion of a loom to which our-improvements are applied, certainparts being omitted in order that our improved automaticshuttling-Inotion may be more readily understood. Fig. 4 is a detailview of part of the apparatus. Fig. 5 is a front vview of theshuttle-box. Fig. 6 is a plan view; Fig. 7, a similar view to Fig. 5with the shuttleguide omitted. Fig. 8 is a back View of Fig. 7; and Fig.9 is a transverse vertical section on the line A B, Fig. 6, these viewsbeing upon an enlarged scale.

In the drawings, 1 denotes the loom-frame 2, the crank-shaft, uponWhichis tteda fast pulley B and a loose pulley 4, the latter beingmounted upon the boss of a narrow pulley 5, which is fitted loose uponthe crank-shaft and placed between the pulleys 3 and 4. Upon the boss ofthe pulley 5 is xed a pinion 6 in gear With a large wheel 7, mountedloosely upon the tappet-shaft 8, and upon the end of this shaft issecured a friction-Wheel 9, into which a dog-catch 10, pivoted upon astud 11,

secured to the wheel 7, engages a spring 12, bearing upon the dog 10.The weft-fork 13 is carried as usual, by a rod 14, secu-red to theweft-fork lever 15, pivoted to a stud 16 on the breast-beam 17, theweft-hammer' 18 being moved at every revolution of the tappet-shaft S byany of the Well-known means. (Not shown.) The ordinary spring-handle 19is tted, as usual, in a slot 20, While a second spring-handle 21 isfitted in a similar slot 22, both in the breast-beam, and this handle 21rests when theA loom is in ordinarywork against one edge of the weftfork lever 15, the spring-handles occupying the positions shown in thedrawings. Upon the failure of Weft the lever 15 is moved by theweft-hain- Iner and forces the handle 2l out of its notch in the slot22, when the spring in the handle rapidly forces it to the right-handend of the slot 22, thus moving a bracket 23, secured to an arm 24,which by a pivoted lever 25 slides the picking-arm 26 and picking neb orcam 27, both mounted loosely upon the tappet-shaft 8, out of contactwith the picking' bowl, (not shown,) which gives motion to thepicking-stick (also not shown) at the opposite side of the loom to theweft-fork and so stops this stick. At the same 'movement of theweft-hammer 1S a rod 23, pivoted to the spring-handle 21, moves by abent rod 29, pivoted to an adjustable collar 30 on the rod 23, anelbow-lever 31, pivoted to a stud on the loom-frame, to one end of whichlever is pivoted a rod 32, which passes through an upright arm 33,pivoted at the bottom of the y frame 34, and two adjustable collars 35are secured on the rodA 32, one on each side of the arm 33, (see Fig.1,) so that the movement of the rod 32 pushes back the pivoted arm 33and With it a horizontal pusher-piece 36, con- ICO bracket 4l, bolted tothe magazine 39. These rods just meet the shuttle-box when the lathe isin its rearmost position. At the same backward movement of the uprightarm 33 a projection 42 upon it comes against a stud 43, mounted to slidein a stationary bracket 44, but held forward by a spring, The oppositeend of this stud enters when the arm 33 is in its rearmost position athread in a worm 45, mounted loosely upon the tappet-shaft 8, as clearlyshown in Fig. 4. To this worm are secured projections 46 47, which restin slots in a boss 4S, fixed upon the tappet-shaft, by which the worm iscaused to rotate and travel along the shaft 8 until the longerprojectionl 47 comes against and moves an arm 49,secured to a pivotedlever 50, held up by a spring 5l. The front end of the lever 50 isconnected by a rod 52 to a plate 53, hinged to the breastbeam 17. At thesame revolution of the worm a bowl 54, carried by it, comes in contactwith a striking-plate 55 and moves forward the upright arm 33 as thelathe is traveling backward.

The bottom of the shuttle-box is formed, preferably, of a solid plate56, and the shuttleguide 57 on the lathe 5S is of metal and has twobosses formed on it, into which are fitted two studs 59 with heads, andupon these studs are coiled springs 60. The inner ends of the studs arealso enlarged and lie flush with the inside-of the guide 57. The back ofthe shuttie-box consists of a plate 61, hinged at 62 to a stationaryplate 63 and held in either position, whether open or closed, by aspring 64, bolted to the lathe.

To close the back of the shuttle -box, a bracket 65 is secured. to thebox, which carries a stud 66, upon which is mounted a bowl 67, and to ashort shaft 68, free to be oscillated upon its axis, is secured a smallbracket 69 and a finger or striking piece 70. A projection 7l on theupper part of the arm 33 cornes against the bracket 69 at certain timesand turns the shaft 63, which is returned to its normal position by acoiled spring 7 2.

rlhe mechanism for knocking oif the ordinary spring-handle 19 andstopping the loom when there are no shuttles in the magazine consists ofa light vertical rod 73, connected to the upper end of the spring-handle19. An adjustable bracket 74 is secured to this rod 73, which isconnected to an arm 75, pivoted on a shaft 76, that extends across theloom and has secured to it at the other side a weighted arm 77, to whichis connected a rod 7S, the top of which is T- shaped and lies in contactwith the lowest shuttle 79 in the magazine, the weight of a singleshuttle being suiiicient to hold the parts in the positions shown inFig. l-that is to say, with the bracket 74 out of the path of theknocking-off finger SO, on the usual stop-rod 31, carried by the lathe.

Upon the failure of weft the action of the picking-stick is arrested,the vertical arm 33 is forced back in the manner described, and

the'pusher-piece 36 is withdrawn from under the magazine, so that thereserve shuttles rest upon the horizontal rods 40, the hinged plate 53is drawn down by the projection 47, pressing down the arm 49, lever 50,and rod 52 opposite to the studs 59 in the shuttle-box, so that when thelathe comes slowly up the studs meet the hinged plate and are pushedback against the shuttle and force it out of its box through the back ofthe box, which is hinged and kept closed by the spring 64, the spentshuttle falling into a suitable receptacle through a chute 82. At thesame revolution of the worm 45 a bowl 54 upon it colnes in contact withthe striking-plate 55 and moves forward the upright arm 33 as the latheis traveling toward the magazine 39 of reserve shuttles, the lowestshuttle of which is by the pusher-piece 36 then moved along thehorizontal rods 40 through the open back into the shuttle box. The sameforward movement of the vertical arm brings its upper portion 7l againstthe bracket 69 and turns the shaft 68, which brings the finger againstthe bowl 67 and shuts down the back 6l of the shuttle-box, which is thenheld closed by the spring 64 that had previously held it open. Thefinger 70 in closing the back 61 comes into contact with thepusher-piece 36 and forces it down on its links 37, the springs 38immediately returning the pusher-piece 36 to its normal position, and asthe upright arm continues its forward movement it carries the rod 32forward-moving the elbow-lever 3l and rods 29 and 23, which force thespringhandle 2l into the notch at the left-hand end of the slot 22,andthis movement of the springhandle 21 draws back the arm 24 and lever 25and cam 26 into the pat-h of thc pickingbowl, which actuates thepicking-stick. The movement of the handle 2l has simultaneously shiftedthe driving-belt fromfthe narrow pulley 5 to the fast pulley 3 andchanged the loom from the slow to the ordinary fast speed while thelathe is upon the back centers, and in consequence of the change ofspeed taking place at this time the loom acquires suliicient speed togive an effective pick to the shuttle. After a new shuttle has beeninserted into the shuttle-box by the pusher-piece 36 the upright arm 33is drawn back into its normal position (see Fig. l) by a coiled spring83. In case the magazine 39 should be empty the rod 78, being no4 longerheld down by the weight of a shuttle in the magazine, will rise and movethe arms 77 and 75, so as to draw down the rod 7 3 and bracket 74, whichlatter comes into the path of the knocking-off finger 8O on the stop-rod8l, and as the lathe comes back the linger 8O meets the bracket, knocksoff the spring-handle 19, and stops the loom.
